[Haskell-beginners] Segmentation fault

[Michael Peternell]

Is there a version 10.8.3?

I downloaded Haskell from the official website at http://www.haskell.org/platform/ . I followed the one and only "Download" link on the homepage. The Wikipedia says that 7.6.2 is the newest version although I cannot find that version on the haskell website. It's hard for me to believe that the development version would be 3 major version numbers ahead, but maybe we are talking about different implementations?

Where can I find the latest version?

Regards,
Michael

I didn't do anything fancy with Haskell, I just downloaded it yesterday and I didn't tamper with any haskell-files outside of my home-directory. The only kernel extensions I have installed are the ones from VMWare Fusion and maybe flux. (i'm not sure if flux involves kernel extensions or how deeply it messes with the OS.)
